Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A method for operating a mobile terminal comprising: receiving by the mobile terminal an operation mode indication from a network, wherein the operation mode indication comprises an indication of a primary transmission mode period of operation during which the mobile terminal operates without need for interference coordination, by the network with other users operating under the network, on an unlicensed frequency band, a secondary transmission mode period of operation during which the mobile terminal operates on predefined resources on the unlicensed frequency band, and an idle transmission mode period of operation during which the mobile terminal is not allowed to conduct any transmissions on the unlicensed frequency band; causing an interfered ratio report to be transmitted to the network, wherein the interfered ratio report is calculated as a total number of interfered symbols over a sensing period; determining whether to operate the mobile terminal as a primary user or a secondary user based on the interfered ratio report, wherein the primary user is configured to operate during the primary transmission mode period of operation and/or during the secondary transmission mode period of operation, and the secondary user is configured to operate during the secondary transmission mode period of operation only; and determining whether to operate the mobile terminal during the primary transmission mode period of operation, the secondary transmission mode period of operation, or the idle transmission mode period of operation.
A method for a mobile terminal to operate on an unlicensed frequency band shared with other technologies, such as WiFi, involves the mobile terminal receiving instructions from the network specifying three modes: a primary mode where the mobile terminal transmits without coordinating with other users, a secondary mode where the mobile terminal transmits using predefined resources, and an idle mode where the mobile terminal doesn't transmit. The mobile terminal transmits a report to the network indicating the amount of interference it detects. Based on this report, the network classifies the mobile terminal as either a primary user (allowed to use both primary and secondary modes) or a secondary user (allowed only the secondary mode). The mobile terminal then determines which mode to operate in based on this classification and network instructions.
2. A method according to claim 1 further comprising: causing operation during the primary transmission mode period of operation.
The method described above for operating a mobile terminal in an unlicensed band, where the mobile terminal receives instructions from the network specifying primary, secondary, and idle modes and is classified as a primary or secondary user based on an interference report, further includes operating the mobile terminal in the primary transmission mode period. This means the mobile terminal is actively transmitting without interference coordination during the designated primary mode timeframe.
3. A method according to claim 1 further comprising: causing operation during the secondary transmission mode period of operation.
The method described above for operating a mobile terminal in an unlicensed band, where the mobile terminal receives instructions from the network specifying primary, secondary, and idle modes and is classified as a primary or secondary user based on an interference report, further includes operating the mobile terminal in the secondary transmission mode period. This means the mobile terminal is actively transmitting using predefined resources during the designated secondary mode timeframe.
4. A method according to claim 1 further comprising: causing operation during the idle transmission mode period of operation.
The method described above for operating a mobile terminal in an unlicensed band, where the mobile terminal receives instructions from the network specifying primary, secondary, and idle modes and is classified as a primary or secondary user based on an interference report, further includes operating the mobile terminal in the idle transmission mode period. This means the mobile terminal refrains from transmitting during the designated idle mode timeframe.
5. A method according to claim 1 , further comprising: causing, when in the primary transmission mode period of operation, a transition to the secondary transmission mode period of operation in an instance in which a primary mode transition timer expires; causing, when in the idle transmission mode period of operation, a transition to the primary transmission mode period of operation in an instance in which a primary mode transition timer expires and there is no activity detected on a wireless local area network; and causing, when in the secondary transmission mode period of operation, a transition to the idle transmission mode period of operation in an instance in which at least one of a quality of service is below a predetermined threshold or a packet loss is detected.
The method for a mobile terminal operating in primary, secondary, and idle modes on an unlicensed band further includes transitioning between modes based on timers and network activity. Specifically, while in primary mode, the mobile terminal switches to secondary mode when a timer expires. When in idle mode, the mobile terminal switches to primary mode if a timer expires and no WiFi activity is detected. Finally, when in secondary mode, the mobile terminal enters idle mode if the quality of service falls below a threshold or packet loss is detected.
